Description

Technical Field

[0001] This utility model relates to the field of solenoid valve technology, and in particular to a high-frequency response solenoid valve with anti-clogging and self-cleaning function. Background Technology

[0002] A high-frequency response solenoid valve is a solenoid valve that can respond at a high frequency (such as 1000Hz), and its design allows it to operate under high-frequency conditions.

[0003] In the field of solenoid valve applications, ordinary solenoid valves often face some problems during use. Particulate impurities in the fluid can easily enter the solenoid valve, affecting its normal operation and service life. Moreover, the connection stability between the solenoid valve and the connecting pipeline is not good. Under high-frequency vibration or pressure fluctuation, the connection is prone to loosening, leading to fluid leakage. In addition, the sealing of the connection is also difficult to guarantee. Under harsh working conditions such as high temperature and corrosion, the sealing effect will further decrease, thereby affecting the stability and reliability of the entire fluid transportation system. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies, such as the accumulation of impurities in the valve body when conveying fluids containing impurities (such as tap water and industrial media), which leads to valve core jamming, sealing surface wear, or reduced flow rate, seriously affecting the performance and lifespan of the solenoid valve. Traditional solenoid valves also lack effective anti-clogging and self-cleaning functions, requiring frequent disassembly and cleaning, resulting in high maintenance costs. The proposed invention is a high-frequency response solenoid valve with anti-clogging and self-cleaning functions.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A high-frequency response solenoid valve with anti-clogging and self-cleaning function includes a solenoid valve body and a connecting pipe. The two ends of the solenoid valve body are an inlet and an outlet, respectively. Both the inlet and outlet of the solenoid valve body are provided with internal threads. One end of the connecting pipe is provided with an external thread. One end of the connecting pipe is threaded to the inlet of the solenoid valve body. A retaining ring is fixedly sleeved on one end of the connecting pipe. The other end of the connecting pipe is provided with a delivery pipe for connecting to an external pipeline. A processing mechanism is provided between the connecting pipe and the delivery pipe. The processing mechanism can prevent clogging inside the solenoid valve body.

[0007] To improve the stability between the connecting pipe and the solenoid valve body, a reinforcement mechanism is also included, which can enhance the stability of the connecting pipe and the solenoid valve body.

[0008] In one possible design, the processing mechanism includes a processing tube and a filter screen, the processing tube being located between a connecting tube and a conveying tube, and the outer side of the filter screen being fixedly connected to the inner wall of the processing tube.

[0009] In one possible design, the reinforcing mechanism includes a movable ring and two bolts. The movable ring is movably fitted onto the connecting pipe. The movable ring has two through holes, and one end of each of the two bolts passes through the two through holes. The solenoid valve body has two threaded holes on one side, and the bolts are threadedly connected to the threaded holes.

[0010] In one possible design, an inlet pipe is fixedly installed at the top of one end of the processing pipe and connected to it, and an outlet pipe is fixedly installed at the bottom of the other end of the processing pipe and connected to it. The inlet pipe and the outlet pipe are located on both sides of the filter screen, and a third valve is installed on both the inlet pipe and the outlet pipe.

[0011] In one possible design, a first sealing ring is fixedly provided on one side of the retaining ring to improve the sealing between the retaining ring and the solenoid valve body.

[0012] In one possible design, one end of the connecting pipe is connected to a first valve via a flange, one end of the first valve is fixedly connected to one end of the processing pipe via a flange, and one end of the conveying pipe is connected to a second valve via a flange, the second valve being fixedly connected to the other end of the processing pipe via a flange.

[0013] In this application, during use, the end of the connecting pipe with external threads is aligned with the internal thread at the inlet of the solenoid valve body. The connecting pipe is slowly rotated to achieve a threaded connection with the solenoid valve body. During the tightening process, the fixed ring and the solenoid valve body compress the first sealing ring to improve the sealing performance. After the threaded connection is in place, the rotation of the connecting pipe is stopped, and the movable ring is moved to the side of the fixed ring. The through hole of the movable ring is aligned with the threaded hole of the solenoid valve body, and the bolt is inserted into the through hole. The bolt is rotated, and the bolt and the threaded hole are threaded together, causing the movable ring to press against the fixed ring, effectively... To prevent the connecting pipes from loosening, the external flushing water pipe is connected to the inlet pipe (via flange connection, i.e., the flanges on both pipes are fixed with bolts). Both ends of the treatment pipe, the inlet pipe, the outlet pipe, one end of the connecting pipe, and the delivery pipe all have flanges with sealing rings installed on them. The external wastewater pipe is then connected and fixed to the outlet pipe via flanges. The first valve is connected to the other end of the connecting pipe using flanges. One end of the treatment pipe is fixedly connected to the other end of the first valve via a flange. One end of the delivery pipe is connected to the second valve via a flange. Finally, the other end of the second valve is fixedly connected to the other end of the treatment pipe via a flange. For standard connection, the external delivery pipeline is connected to the delivery pipe via a flange, and then the external pipeline is connected to the outlet of the solenoid valve body. After the pipeline connection is completed, it is put into use. During normal delivery, the first and second valves are open, and the two third valves are closed. The fluid (e.g., water) in the external delivery pipeline is delivered to the solenoid valve body through the delivery pipe, treatment pipe, and connecting pipe, and then discharged through the outlet of the solenoid valve body. If the fluid contains impurities, the filter screen will intercept the impurities to reduce the possibility of blockage in the solenoid valve body. When the filter screen needs to be cleaned (e.g., if the water flow is too low, or for regular cleaning), the first and second valves are closed, and the third valves on the inlet and outlet pipes are opened. Water from the external flushing water pipeline enters the treatment pipe through the inlet pipe and flushes the filter screen in reverse. Impurities are discharged through the outlet pipe. After flushing, the third valve on the outlet pipe is closed, and the filter screen is self-cleaned by flushing with water. The filter screen can be made of stainless steel, and the specific material can be selected according to actual needs. The types of the first, second, and third valves can be selected according to actual needs. It should be noted that the solenoid valve body (solenoid valve) needs to be controlled by an external controller and powered by an external power source during use.

[0014] The beneficial effects of this utility model are as follows:

[0015] In this invention, the high-frequency response solenoid valve with anti-clogging and self-cleaning function can intercept particulate matter and impurities in the fluid by setting a filter screen inside the processing pipe. This reduces the amount of impurities entering the solenoid valve body from the source, preventing valve core jamming, sealing surface wear, or flow channel blockage, thus extending the service life of the solenoid valve. The interception effect of the filter screen can maintain the cleanliness of the internal flow channel of the solenoid valve, ensuring the stability and flow accuracy of fluid delivery, avoiding flow reduction or pressure fluctuation caused by impurity accumulation, and improving the long-term operational reliability of the solenoid valve.

[0016] In this utility model, the high-frequency response solenoid valve with anti-clogging and self-cleaning function is connected to an external flushing water source through the inlet and outlet pipes. After closing the first and second valves, the filter screen is flushed in reverse, and the intercepted impurities are discharged from the outlet pipe, realizing online cleaning without disassembling the solenoid valve, which greatly reduces maintenance time and labor costs.

[0017] In this invention, the processing mechanism can intercept particulate matter and impurities in the fluid, reducing the amount of impurities entering the solenoid valve body from the source, avoiding valve core jamming, sealing surface wear or flow channel blockage, and extending the service life of the solenoid valve. By connecting to an external flushing water source through the inlet and outlet pipes, the filter screen can be backwashed for self-cleaning without disassembly. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] In one embodiment: Refer to Figure 1-4 A solenoid valve, used in the field of solenoid valves, includes: a solenoid valve body 1 and a connecting pipe 2. The solenoid valve body 1 has an inlet and an outlet at both ends, both with internal threads for connection to external pipelines. One end of the connecting pipe 2 has an external thread, which is screwed tightly onto the inlet of the solenoid valve body 1 to form the initial part of the fluid passage.

[0025] A retaining ring 10 is fixedly fitted onto one end of the connecting pipe 2 near the solenoid valve body 1. The outer diameter of the retaining ring 10 is larger than the outer diameter of the connecting pipe 2, for use with subsequent reinforcement mechanisms. The other end of the connecting pipe 2 is connected to the first valve 4 via a flange. The other end of the first valve 4 is fixedly connected to one end of the processing pipe 5 via a flange. The other end of the processing pipe 5 is connected to the second valve 7 via a flange. The other end of the second valve 7 is fixedly connected to the delivery pipe 8 via a flange. The delivery pipe 8 is used to connect to an external fluid delivery pipeline.

[0026] Modular assembly of components is achieved through flange connection, facilitating disassembly and replacement; the first valve 4 and the second valve 7 are used to control the flow of fluid and support switching between normal delivery mode and backflushing mode.

[0027] The processing mechanism includes a processing pipe 5 and a filter screen 13. The processing pipe 5 is a cylindrical structure located between the connecting pipe 2 and the conveying pipe 8. The filter screen 13 is fixedly installed on its inner wall by welding or snap-fit. The pore size of the filter screen 13 is designed according to actual working conditions, for example, 50-200 mesh, to intercept particulate impurities in the fluid.

[0028] An inlet pipe 6 is welded to the top of one end of the treatment pipe 5, and an outlet pipe 12 is welded to the bottom of the other end. The inlet pipe 6 and the outlet pipe 12 are located on both sides of the filter screen 13. The inlet pipe 6 is used to connect to an external flushing water source, and the outlet pipe 12 is used to discharge the wastewater and impurities after flushing. A third valve is installed on both the inlet pipe 6 and the outlet pipe 12 to control the flow of flushing water.

[0029] Normal delivery: First valve 4 and second valve 7 are open, third valve is closed, and fluid sequentially passes through delivery pipe 8, second valve 7, processing pipe 5, first valve 4, and connecting pipe 2 into solenoid valve body 1, and is finally discharged from the outlet; filter screen 13 intercepts impurities in the fluid to prevent them from entering the solenoid valve.

[0030] Backwashing: When a decrease in flow is detected or during regular maintenance, close the first valve 4 and the second valve 7, and open the third valve on the inlet pipe 6 and the outlet pipe 12. External flushing water enters the treatment pipe 5 through the inlet pipe 6 and backwashes the filter screen 13. Impurities are discharged from the outlet pipe 12 with the water flow. After flushing is completed, close the third valve and restore the normal conveying mode.

[0031] To improve the connection stability between the connecting pipe 2 and the solenoid valve body 1, this utility model designs a reinforcing mechanism, including a movable ring 3 and two bolts 9. The movable ring 3 has a circular structure and is movably sleeved on the connecting pipe 2, allowing it to slide along the axial direction of the connecting pipe 2. Two through holes are provided on the movable ring 3, and one end of each of the two bolts 9 passes through the through holes.

[0032] Two threaded holes 11 are provided on the side of the solenoid valve body 1 near the inlet, and the position of the threaded holes 11 corresponds to the through hole of the movable ring 3. After the connecting pipe 2 is threadedly connected to the solenoid valve body 1, the movable ring 3 is slid to the side of the fixed ring 10 so that the through hole is aligned with the threaded hole 11. Then the bolt 9 is screwed into the threaded hole 11 and tightened so that the movable ring 3 is tightly pressed against the fixed ring 10.

[0033] The mechanical locking action of bolt 9 prevents the connecting pipe 2 from loosening due to high-frequency vibration or pressure fluctuations; at the same time, the cooperation between the movable ring 3 and the fixed ring 10 enhances the structural strength of the threaded connection and extends its service life.

[0034] This application is applicable to the field of solenoid valves, and also to other fields to which this application applies.

[0035] In another embodiment: Reference Figure 1-4 High-frequency response solenoid valve with anti-clogging and self-cleaning function:

[0036] To improve the sealing between the connecting pipe 2 and the solenoid valve body 1, a first sealing ring 14 is embedded on the side of the retaining ring 10 near the solenoid valve body 1. The first sealing ring 14 is made of high-temperature resistant and corrosion-resistant rubber or fluoroplastic material, and its cross-section is O-shaped or rectangular.

[0037] When the connecting pipe 2 is screwed tightly onto the solenoid valve body 1, the first sealing ring 14 is compressed, forming a seal.

[0038] However, as is well known to those skilled in the art, the solenoid valve body (i.e., the solenoid valve) is existing technology, and the working principle and wiring method of the solenoid valve are commonplace. They are all conventional methods or common knowledge, and will not be elaborated here. Those skilled in the art can make any selections according to their needs or convenience.

[0039] The accompanying drawings in this application are for illustrative purposes only. The dimensions and shapes of the components shown are not actual limitations but are merely schematic representations. In actual implementation, the components can be reasonably configured and adjusted according to specific needs and actual conditions.

[0040] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
